Night Skies And Petroglyphs

From Harun Mehmedinovic and Gavin Heffernan at – Ancestral Nights. Filmed for Skyglow Project, a crowdfunded endeavor illustrating effects of light pollution on dark skies. Lose yourself in night skies and petroglyphs….

Carvings, structures and petroglyphs captured in this video represent ancient observance of night skies by Native Hawaiians, Paiute people of California and Puebloans of the Southwest.

Concentric white circles filling the sky over large rock with symbols carved into it.

“These petroglyphs and structures reflect the long standing interest in ancient astronomy which grew stronger as many of the tribes went from the hunter-gatherer to the agrarian societal orders. From references to the sun carved in the rock, and interest in using the sun to predict seasons (entire buildings built to serve as sundials and calendars, a critical element in the farming communities) to those of 13 moons (lunar annual calendar), to carvings of stars and constellations, interest in celestial bodies is ever present across the indigenous communities of the United States.” – Harun Mehmedinovic

Noctilucent Timelapse by Adrien Mauduit

Noctilucent clouds are a weather phenomenon unique to summer months at latitudes between 50 and 70 degrees north and south of the equator. Inhabiting the mesosphere at altitudes of 75-86 kilometers, science regards noctilucent as highest clouds in Earth’s atmosphere. Too faint to be seen in daylight, there’s good reason why they’re known as luminous or night shining clouds. Noctilucent clouds can only be illuminated by sunlight below the horizon at astronomical twilight when lower levels of the atmosphere are in Earth’s shadow. Learn more at –
